I'm looking for a cycle analyst I have a lyen 18fet controller and a crystalyte crown 4080 and as far as I know I need the CA to use it . I always use sabvoton or fardriver so I've never used a ca . If you have one or a good controller 80amp 84v
Cycle analyst needed 84v it's for a lyen 18fet controller

A CA is not a required part of that kind of system.
The Lyen controllers don't have any functionality that is integrated with the CA to operate, though many of them have a connector that can plug into a CA to allow you to monitor power usage, battery voltage, current, speed, distance, etc, by using the internal shunt built into the controller.
If you are needing a display for the controller, in the same sense as other controllers that use one to program the controller, the CA isn't that, and cannot do that. I don't think any Lyen controller is capable of that.

Ok that's what I was unsure about I know the lyen can be programmed in the same manor as a fardriver on the PC but thought it may need the CA as the display. I can just run a voltage display to use the setup . The cycle analyst would give me all the information and adds another level of tuning for throttle battery etc .
I have a Cycle Analyst from an original Stealth Bomber that used this type of controller. I also have the original 18FET controller. I’m located in Europe, and I can send you some photos if you’d like.
But… what Amberwolf told you is true, I don’t recall there ever being any real integration between the controller and the display beyond just reading data.

Not even that. There is no communication between the CA and any controller (not even the Phaserunner / etc). It doesn't read any data at all.
Everything in the CA is calculated internally based on it's various analog inputs.
It is not a "display" in any sense that controllers use displays for.
I'm not 100% sure about that, if I remember well the CA is connected using 4 wires to and only to the controller, maybe this wires are 2 for voltage, 2 for the internal shunt on the controller but I can check tomorrow and report it back here.
There are 6 wires, 4 of them signals, the CA can have in the typical "CA connector" to a controller:
Battery postitive(from controller to CA)
Battery Negativve(from controller to CA)
Shunt + (from controller (or separate external shunt) to CA)
Shunt -(from controller (or separate external shunt) to CA)
Throttle signal (out from CA to controller)
Speed signal (out from controller to CA (usually directly from one of the motor halls))
None of the information the CA displays comes from the controller itself. It's all measured and/or calculated internally from those inputs and the others it has that don't connect to the contyroller.
The CA has other connections available, but none of them are data communications with controllers, which is what is required to be a display for a controller in the sense that cotnrollers with displays use them.
The only serial connection it has is for programming it, and can also be used to realtime output a continuous data stream of it's calculated and measured readings...but it can't receive any input from the controller this way, and it can't send anything to the controller to cause the contyroller to do anything this way.
It's only way to modify controller behavior is to modulate the analog throttle signal, which is exactly waht a throttle does, not what a controller display woudl do.

OT, but based on the above, I had a thought:
if you were to custom-write firmware for a controller, or create an MCU-based device to translate for nonupdateable controllers, you could use the CA as an input device to it to change controller settings or modes, taking the realtime data output of the CA to take one or more of it's inputs information and use that to change parameters on the controller. As long as the input from the CA is one whose data can be included in the realtime output of the CA on it's serial port, and the update speed of that data is sufficient for the level of control desired.
Unfortunately there's still no simple way I can think of to use the CA to display feedback from the controller in response to this data. If simple numeric feedback is sufficient, the speedo signal could be used to display a number code on the CA, but it's the only "always visible" (on the main screen) data field that could be directly input from the outside world.
Only mentioned here because the misunderstanding of how the CA and controllers interact has come up before a number of times, and that's why I posted the stuff I did initially up above.

I'm kinda confused , I understand that the controller is programmed via the USB serial cable. I was under the understanding that the CA could change various things like throttle parameters DC amp phase amps low voltage cut off etc. If I'm understanding it correctly you're saying that the CA might change those values but it's not actually changing anything of the controller correct.What threw me off was the proprietary cycle analyst connection it had me thinking that it was designed to be used as that for a display non the sensitive changes the controller but in the sense that it's already wired for it to use that. I should just save myself some money then and do what I did with a sabvoton or the far driver and use a generic display to see the voltage and speed .
Sorry for the poor spelling.
Depends on the controller. At least some Lyens can be.
Other controllers, depends--every one out there is different, potentially, than every other, even from the same manufacturer.
The CA is a "computer" in itself. It takes all it's various inputs, analog and on/off switches, and processes them according to the settings you have chosen within the CA setup or menus, and outputs a throttle signal to operate "any" controller, based on all that.
Well, it has a display (LCD) as part of it, and it does display data relevant to the whole system, but none of that info comes directly from the controller, and it doesn't send any data to the controller (unless you count an analog throttle signal as data
).If all youw ant is voltage and speed, you can use a bike speedo for a few dollars, and a really cheap voltmeter for another few dollars. Probably less than $20 total if you look around. Possibly half that if you poke around at thrift stores or used items on ebay/etc.
